Answer:

Mesozoic era

Explanation:

The mesozoic is but one of the eras on the geologic timescale. This era spanned between 252 - 66million years ago.

It is bounded by two major mass extinction events. The Permian- Triassic extinction wiped about 90% of a life on earth. The other extinction is the Cretaceous-Paleogene which resulted in the demise of the dinosaurs.

During the mesozoic, the continents also formed from pangea and they all drifted to their present day position.

There are 3 periods in the mesozoic era:

Triassic - Jurassic - Cretaceous.

The mesozoic is known as the age of reptiles and dinosaurs.

The first flowering plants came towards the end of the era. The era was intially dominated by conifers.

This is also the age of the first birds.

The ability of vibrio cholerae to cause disease depends on a number of factors. What are general requirements for any organism t
Svetllana [295]
<h2>Disease </h2>

Explanation:

  • Pathogenicity is the ability to produce disease in a host organism
  • Microbes express their pathogenicity by means of their virulence, a term which refers to the degree of pathogenicity of the microbe
  • The relationship between a host and a pathogen is dynamic, since each modifies the activities and functions of the other
  • The outcome of such a relationship depends on the virulence of the pathogen and the relative degree of resistance or susceptibility of the host, due mainly to the effectiveness of the host defense mechanisms
  • Hence, general requirements for any organism to cause disease within a host are: evasion of host defenses , gaining access to the host via a portal of entry, adherence to host tissues

what does the term 2pq represent in the hardy-weinberg equation? the frequency of homozygous recessive individuals the frequency
Nostrana [21]

The term 2pq represented in the hardy-weinberg equation is the frequency of heterozygotes and is denoted as option D.

<h3>What is Hardy-weinberg equation?</h3>

This mathematical equation is used to calculate the genetic variation of a population at equilibrium and can be seen below:

p² + 2pq + q² = 1

where

p² is dominant homozygous frequency (AA)

2pq is heterozygous frequency (Aa)

q² is recessive homozygous frequency (aa).

The 2pq can be seen as the heterozygous frequency which is therefore the reason why option D which is frequency of heterozygotes was chosen as the most appropriate choice.
